I review Peter Weir's The Way Back, with Ed Harris and Colin Farrell as escapees from a Soviet Gulag camp in Taki's Magazine:

The truth is that a vast number of survivors walked home from Soviet camps in the 1940s and 1950s, including a distant in-law of mine. He had been an Italian soldier posted to fight General Patton's invading American army. When Mussolini was overthrown, peace was declared and he deserted. But the occupying Germans rounded him up and sent him to the Eastern Front, where the Soviets captured him. When the war ended, the camp commandant opened the gate and gestured in Italy's general direction. It took him two years to trudge home.
